SpaceX Falcon Heavy rocket to launch NASA’s Roman Space Telescope
NASA has chosen SpaceX’s Falcon Heavy rocket to launch its next major space telescope, a wide-field observatory that should directly complement the brand new James Webb Space Telescope.
Originally known as the Wide Field InfraRed Survey Telescope (WFIRST), NASA recently renamed the mission in honor of Nancy Grace Roman, a foundational force behind the Hubble Space Telescope. Fittingly, the Roman Space Telescope’s basic design is reminiscent of Hubble in many ways, owing to the fact that the mission exists solely because the US National Reconnaissance Office (NRO) chose to donate an unused multi-billion-dollar spy satellite – a satellite that was effectively a secret Earth-facing version of Hubble.
However, thanks to decades of improvements in electronics, electromechanics, and the instrumentation side of spacecraft and space telescopes, RST will be dramatically more capable than the Hubble telescope it resembles. And now, after a several-year fight for survival, the Roman Space Telescope officially has a ride to space – SpaceX’s Falcon Heavy rocket.
Falcon Heavy continues to be a bit of a paradox, winning contract after contract for increasingly high-value flagship launches despite having not launched once in more than three years. It’s a bit of a self-fulfilling prophecy, at this point, as the major missions that are increasingly being entrusted to Falcon Heavy are far more likely to run into significant spacecraft-side delays. At one point in late 2021, for example, SpaceX had five Falcon Heavy launches tentatively planned in 2022 – all but one of which had already been delayed several months to a year or more. Seven months into 2022, not one of those missions has launched and it’s looking increasingly likely that Falcon Heavy will be lucky to fly at all this year.
Nonetheless, the Roman Space Telescope joins an impressive manifest that includes the multi-billion-dollar GOES-U weather satellite, NASA’s ~$5 billion Europa Clipper, two modules (HALO and PPE) of a Moon-orbiting space station, NASA’s Psyche asteroid explorer, a large Astrobotic Griffin lander carrying NASA’s VIPER Moon rover, two large geostationary communications satellites, and three missions for the US military. RST is the rocket’s 11th launch contract between now and the mid-2020s.
Despite having a similar resolving power, RST’s primary wide-field instrument will have a field of view 100 times greater than Hubble, meaning that the new telescope will be able to gather magnitudes more data in a similar time. Its primary goals include measuring “light from a billion galaxies over the course of the mission lifetime” and performing “a microlensing survey of the inner Milky Way to find ~2,600 exoplanets.” A second coronagraph instrument will “perform high-contrast imaging and spectroscopy of dozens of individual nearby exoplanets.” According to the Jet Propulsion Laboratory, “the Coronagraph provides a crucial stepping stone in the preparation of future missions aiming to [directly] image and characterize Earth-like planets [that are] 10 billion times fainter than their host star.”
According to NASA, “the telescope’s science program also includes dedicated investigations to tackle outstanding questions [about the nature and] effects of dark energy and dark matter, as well as a substantial general investigator program to enable further studies of astrophysical phenomena to advance other science goals.”
Because RST is also focused on infrared wavelengths of light, it could be an excellent companion to the James Webb Space Telescope (JWST). Whereas RST is a wide-field survey observatory that aims to observe and catalog billions of galaxies, stars, and planets, JWST’s far larger mirror is optimized for up-close observation of individual targets or deep gazes into tiny swaths of sky. RST could ultimately work a bit like an MRI or CAT scan to JWST’s biopsy, telling the surgeon where to look but only hinting at what it might find.
According to NASA, the ~$4.3 billion space telescope’s Falcon Heavy launch contract will cost an exceptionally steep $255 million to send the spacecraft to the Sun-Earth L2 Lagrange point about 800,000 kilometers (~500,000 mi) from Earth. NASA’s contract to launch the even more expensive Europa Clipper spacecraft all the way to Jupiter with a fully-expendable Falcon Heavy rocket is expected to cost less than $180 million.
NASA’s press release also claims that RST will be ready to launch as early as October 2026. A different press release from September 2021 did not mention the 2026 target and only noted that RST’s launch is scheduled no later than May 2027.

Why SpaceX is finishing another space-internet system that isn’t Starlink
SpaceX launched three final O3b mPower satellites Sunday, finishing a lesser known SES satellite network.
SpaceX had an 87 minute window opening at 2:49 p.m. Eastern on Sunday to fly a Falcon 9 out of Cape Canaveral carrying the final three satellites for SES’s O3b mPower constellation, a project that has taken more than a decade to finish since Boeing and SES first signed SpaceX on for the work.
Unlike the thousands of Starlink satellites SpaceX has stacked into orbit over the years, O3b mPower flies in a different neighborhood entirely. The three new satellites, tagged F11, F12 and F13, are headed for medium Earth orbit at roughly 5,000 miles up, more than ten times higher than Starlink’s shell around 340 miles but still a small fraction of the 22,000 miles where old school geostationary satellites sit. That middle position is the whole point, because a satellite that far out needs far fewer siblings to blanket the globe than a low orbit constellation does. Essentially, SES only needed 13 satellites total to build a network offering quick, steady service that used to require thousands of spacecraft.
With most people having heard plenty about Starlink and almost nothing about O3b mPower, SES and SpaceX already blend the two networks for some customers. Both SpaceX and SES sell satellite broadband, but they’re aimed at different buyers. Starlink is built for volume, direct to consumers, RVs, homes, small businesses, plus a growing aviation and maritime business. O3b mPower skips consumers entirely and sells enterprise grade connectivity to airlines, cruise lines, offshore energy operators, telecoms needing backhaul, and governments, priced and provisioned more like a dedicated circuit.
A 2023 partnership lets cruise ships combine Starlink’s speed with O3b mPower’s steady capacity depending on what a ship needs at a given moment. Sunday’s completed 13 satellite constellation effectively finishes the medium orbit half of that pairing, years after.
Sunday’s mission was already a something on SpaceX’s manifest well before O3b mPower entered the picture. This flight marked its 29th trip to orbit, a history that includes two crewed Axiom missions, the European Space Agency’s Euclid telescope and 22 separate Starlink batches. SpaceX has landed boosters on the droneship A Shortfall of Gravitas so often that Sunday’s touchdown attempt, if it went as planned, was set to be the 661st successful Falcon booster landing to date.
For a company that pushed the Starlink constellation past 11,000 satellites back in August, almost entirely through bulk launches from California, Sunday’s flight was a reminder that SpaceX’s schedule still has room for someone else’s satellites too. SES gets a finished network built for a narrower set of customers, and Falcon 9 gets one more line on an already long resume.

Tesla gives the Roadster an official “Go for launch” demonstration date
Tesla teased an October 1 Roadster reveal, reviving years of delayed SpaceX thruster hover promises.
Tesla teased an October 1 event date for its next generation Roadster, posting an image on X Saturday that shows the car lit up like it is sitting on a launch pad, with the date “10.01” stamped across the bottom and the caption “Go for launch.” A countdown clock on Tesla’s Roadster order page now points to the same date, which falls on a Thursday. The company has not said where the event will happen or whether it will be streamed at the moment. Stay with us @Teslarati for live updates.

Tesla has since sent formal invitations to reservation holders confirming the event will take place in Waco, Texas, about 90 minutes north of its Austin headquarters, based on a digital ticket shared on X by Sawyer Merritt. Tesla did not name the exact venue, though Waco sits close to SpaceX’s McGregor, Texas, rocket test site, previously reported as the planned location for a Roadster thruster demonstration. The invite sets the reveal for 8:30 p.m. Eastern on October 1, requires RSVPs by midnight on September 16, and limits entry to guests 21 and older. Invitations are non-transferable.
The tease follows nine years of a project defined by unimaginable specs along with slipped dates. Musk first showed the second generation Roadster in November 2017 as a surprise reveal at the end of the Tesla Semi event, promising a 0 to 60 mph time under two seconds, a top speed above 250 mph, 620 miles of range from a 200 kWh battery, and production starting in 2020. At last November’s shareholder meeting, Musk set an April 1 demo date and joked the choice gave him “deniability” if it slipped again, which it did, moving first to late April, then to “a month or so,” then to August.
Tesla Roadster SpaceX Package’s 1.1-second 0-60 mph launch visualized in concept video
Whatever Tesla shows on October 1 is expected to center on the SpaceX developed thruster package Musk has described since 2018. Internally code named A71, a nod to the Lockheed SR-71 Blackbird, the system reportedly uses cold gas thrusters fed by a composite overwrapped pressure vessel, the same tank design SpaceX uses on Falcon 9. Musk has said a thruster equipped Roadster could hit 60 mph in about 1.1 seconds under roughly 2.75 g of launch force, well past the 1.9 second figure quoted for the standard car. That version reportedly will not be street legal and has reportedly been discussed as a limited run sold through a track only program.
The standard Roadster is still expected to carry the original $200,000 base price and $250,000 Founders Series tier, both set when Tesla opened $50,000 and $250,000 reservations in 2017. Tesla VP of Vehicle Engineering Lars Moravy has confirmed production will happen at Gigafactory Texas, with Musk targeting 2027 or 2028, 12 to 18 months after whatever the company demonstrates next month.
Tesla is planning to roll out some pretty significant safety and accident avoidance features with Full Self-Driving version 15, which will be the next major FSD deployment from the company.
Tesla AI lead Ashok Elluswamy used a near-miss this week to preview what the company says is the next leap in Full Self-Driving.
In response to a driver whose car had swerved away from another vehicle pulling out of a parking lot, Elluswamy wrote that he was glad the owner was safe and that “even earlier prediction of hazards, even faster reaction time and overall significantly better safety and collision avoidance” would arrive with FSD v15.
Glad you are safe. Even earlier prediction of hazards, even faster reaction time and overall significantly better safety and collision avoidance coming as part of the next big upgrade (v15).

The comment landed as Tesla continues to treat software as the primary safety upgrade path. v15 is described internally as a larger architectural step, with a much bigger neural network and tighter coupling between prediction and control.
The company has already begun using early v15 software in some robotaxi operations while rolling out safety features such as Automatic Collision Evasion into current customer cars, allowing the driving stack to intervene even when the driver is in manual control.
Tesla is rolling out a new FSD version with a massive safety addition
Tesla’s published telemetry is the backbone of its safety argument. In recent North American Vehicle Safety Report data, vehicles with FSD (Supervised) engaged traveled roughly 5.1 million to 5.7 million miles between major collisions, defined as airbag-deployment events.
Tesla’s estimate of the U.S. average over the same period is about 699,000 miles per comparable crash. That is the comparison Tesla often frames as roughly seven times fewer major collisions.
A tighter comparison uses the same Tesla fleet. Cars driven manually with active safety features such as automatic emergency braking still recorded a major collision about every 2.1 million miles. Against that baseline, FSD’s advantage shrinks to roughly 2.4 to 2.7 times fewer severe crashes, which independent researchers argue is the more apples-to-apples figure.
European data released in 2026 pointed in the same direction: Tesla reported FSD as 3.5 times safer than manual driving in the Netherlands and 4.1 times fewer collisions than manually driven Teslas with active safety across more than 100 million kilometers in five approved countries.
Those numbers do not settle every debate. NHTSA’s Standing General Order still shows Tesla accounting for the large majority of U.S. Level 2 driver-assist crash reports, in part because the fleet logs far more assisted miles than rivals. Critics also note that Tesla’s “U.S. average” mixes crash definitions and driving mix.
Even so, Tesla’s own same-car comparisons, plus lower rates of automatic emergency braking and harsh maneuvers when FSD is engaged, are the evidence Elluswamy is pointing to when he says v15 will push prediction and collision avoidance further. The claim is not that software already eliminates risk. It is that each major version is meant to widen the gap between the system and an unaided human driver.
